Alright, first of all, thank you to parinumal07 for the first review. OK, here goes with the next chapter.

Disclaimer: Unfortunately, Sam and Dean are not mine, the twins however, are.


The man ran; the bloody knife still in his hand, his broken elbow cradled against his body. Sam caught him as he tried to run past and grasped his jacket. The man turned, and Sam felt the blade slice across the inside of his forearm. He hissed in pain and grasped the hand holding the knife, twisting the blade onto the man. He watched as the vicious light in the man's eyes died and he fell to the floor, his life blood bubbling from the wound in his chest.

"No! Please tell me he's still alive." Alyssa's cry shocked Sam and he looked at the man on the floor, the lifeless, staring eyes telling him that he was most definitely dead.

"No, he's dead. Why do you want him alive?"

"He could have saved her. You'll have to help me instead."

"How?"

"No time to explain, come here." The command in her voice jolted Sam into action and he ran to the girls, kneeling on Kia's other side.

The girl, who only moments before had been smiling at him was lying in her sister's arms, dark blood pulsing from the deep wound just below her ribcage. As he watched, her head tossed and her eyes opened, her breath coming in pained gasps.

"Alyssa?" She squeezed her eyes shut in pain.

"Shh, it's O.K, sweetie. I'm gonna make it better." Alyssa stroked her sister's pale face tenderly, pain evident on her own.

Dean crouched down next to the girl and looked at the wound.

"She's dying." He felt sympathy for Alyssa as she held her dying twin.

"I know." Alyssa turned away from Dean, looking up at Sam. "I hope you're strong." Without warning her hand flashed out, resting on the side of Sam's neck, Sam shuddered, his breath coming in gasps.

"What are you doing?" Dean watched as Sam's body shook.

"Saving my sister." Alyssa did not look away from Sam.

"By killing my brother?"

"This won't kill him, now shut up." Alyssa placed her hand over the wound in Kia's body; dark blood pulsed through her fingers.

Dean could only watch as Sam shuddered again and the blood stopped flowing. Dean's eyebrows raised as Kia's eyes opened and she propped herself up on one elbow.

"Alyssa that's enough, I'm fine."

"Are you sure?" Alyssa had not removed her hand from Sam's neck.

"Yes, let him go before you take too much." Kia reached up and grasped Alyssa's wrist, pulling her hand away from Sam. Sam fell back, his breaths shallow. Dean ran to him, grasping his little brother's shoulders.

"Sammy, you O.K?"

"My name is Sam."

"Yup, you doing just fine." Dean turned to the twins. "What the hell just happened? You were dying."

Kia looked up at him, meeting his eyes. "Not for the first time."

"How did you do that? No, scrap that, what did you do?"

"We shouldn't tell them." Alyssa's eyes were guarded as she looked at the brothers.

"It's a bit late for that; they've already seen it first hand." Kia looked at her sister and Alyssa sighed, nodding. "Alright, we'll tell you, but first we need to get out of here."

Dean nodded. "Alright, but you're a bit obvious." He looked pointedly at the blood that covered Kia's clothes.

"Here." Sam pulled off his hoody and handed it to Kia; she took it gratefully and pulled it on.

"Thanks, our place is just down the street. Come on, let's go."

They left the alley, thankful that the streets were empty and walked quickly through the city. They had only been walking for a few moments when the girls led them into an apartment building. They followed them up the stairs, pausing for a moment as they unlocked a door before slipping inside the apartment.

The inside was spacious, a punch bag hung near one corner and various knives hung on the far wall. Two doors were along each side wall, another door next to the knives. In the centre of the room were two couches, the twins moved to one, Kia sitting down while Alyssa leaned against it. Sam sat on the second couch across from Kia while Dean stood beside him.

"Alright, so what's going on?" Dean reiterated his previous question.

Alyssa took a deep breath before answering.

"When we were about eight, Kia and I discovered that we had…I suppose you could call them powers, god I hate that word."

"So these…powers, what are they?" Sam was curious.

"When I want to, I can drain a person's life force through touch, as I did with that guy in the alley, and with you." Alyssa had looked at Sam as she spoke.

Dean looked up, fury written on his face. "What, so you just decided to take Sam's life force? You could have killed him."

Alyssa stood up and moved towards Dean, her dark eyes blazing.

"My sister was dying, Dean. What would you have done if it was Sam? And I know how to control my gift, thank you very much."

"Oh right, so your sister having to stop you, that was you in control?"

"Dean, stop." Sam tried to stop his brother's rage.

"No, Sam, she could have killed you." He turned on Alyssa as she advanced on him again.

"Alright, that's enough; get a hold of your tempers, both of you and not another word!"

Kia had risen from her seat and moved to stand between Dean and Alyssa, her dark eyes angry and her jaw set. She turned to Alyssa and they faced each other for a second before her twin sat down, not bothering to argue. When Kia turned to Dean he opened his mouth as though to argue but she shook her head.

"Dean, do not start with me, you will not win." Kia's tone brooked no argument and Dean raised his hands in defeat and backed off.

Sam looked on as Kia silenced his brother with no more than a few words, she was a force to be reckoned with even while swamped in his hoody which was far too large for her, and he was impressed. He looked at Kia.

"You mentioned that you both had gifts, what are yours?"

"I can give life force."

"What do you mean, give?" Kia looked at Dean, satisfied that he was not about to go crazy again and sat down.

"That cut on your arm." She reached out her hand, her dark gaze meeting Sam's. He hesitated before reaching out the arm that had been cut.

Kia took his hand in her own and rolled his sleeve back, he winced as she pulled his jacket away from the cut, causing fresh blood to trickle from the wound. The brothers watched, as Kia placed her hand on Sam's arm and took a deep breath. In a few seconds the flow of blood stopped and the cut closed, disappearing without leaving a mark. Sam looked at his arm, then up at Kia, his face thoughtful.

"You're her balancing force."

"Yeah." Kia's voice was quiet as she met Sam's gaze. They sat looking at each other, Sam's hand still resting in Kia's. They looked up as Dean moved forwards, their hands dropping apart.

"Alright, I hate to break up this little Kodak moment, but I gotta ask. What do you two use your powers for?"

"Dean you're not suggesting…" Sam turned to his brother incredulous.

"I gotta, Sammy. When she was taking from you, she didn't leave a mark, what with all these unexplained deaths, I'm thinking I wanna know."

"Dean…"

"No it's O.K, Sam, if Dean wants to know, then I'll tell him. I did kill all of those men." Alyssa's gaze did not leave Dean's as she spoke.

"That was murder."

Alyssa stood once more, facing Dean.

"No! That was pest control. They all either tried to hurt us or we caught them hurting others. You tell me, Dean, if you found a guy in the act of raping some poor girl, what would you do?"

"She has a point, Dean. You would be the first to waste them."

Dean sighed and shook his head; he knew that Alyssa had a point and that Sam was right. He would be the first to put a bullet into any guy he caught attacking a girl like that.

"And you haven't killed anyone else?"

"No one." Her gaze was steady.

"Alright, I believe you." He turned to Kia. "And you, what do you use yours for?"

"Healing the people we help."

"You can heal anyone?"

"Not quite, when I heal someone I have to give them what life force we have; if I were to heal something too serious it would be too much."

"Alright." Dean rubbed his hand across his face, suddenly feeling very tired. "I don't know about you, Sam, but I'm shattered, I'm going back to the motel."

"Yeah, sure." Sam stood and walked with Dean to the door.

Kia walked with them and Dean took one look at the girl and his brother before deciding to go and wait in the car. Kia looked up at Sam, a small smile on her face.

"So do you want this back?" She indicated the hoody that she was still wearing.

"No, it's alright; I'll get it from you tomorrow or something."

"Sure, call me when you want it back." They smiled at each other and Sam turned to leave, he smiled all the more when her fingers brushed his as he left the apartment.

Dean looked at his brother as he got into the car. "Where's your hoody?"

"I let her keep it, I'll get it back tomorrow."

"And that wouldn't be an excuse to see her again would it now?"

"Bite me."

"Come on, man, it's obvious you like her." Sam rolled his eyes and Dean grinned as he started the car, heading for the motel.

Back in the motel Dean looked thoughtful; he glanced over at Sam who sat on his bed.

"What was it like when she took your life force from you?" Dean knew his brother would need no more detail in the question.

"I dunno…I couldn't move, I could feel myself getting weaker, but I don't really know how to describe it." Sam's eyes were distant as he thought again about what had happened.

"Hey, what did you mean earlier?"

Sam looked up. "When?"

"You said something about Kia being Alyssa's 'balancing force' what was that about."

"Equals and opposites."

"Huh?"

"Did you ever pay attention in school? It's one of the most basic laws of physics: 'For every action there is an equal and opposite reaction.' Alyssa takes life, Kia gives it, and they balance each other out."

"What are you? A walking encyclopeadia?"

"Apparently."

"Well at least you've got the hots for the one that won't kill you." Sam raised his eyebrows but did not reply, realising that Dean had a point.

"So, what are we going to do, now that we found what killed those men?" Sam could not help but wonder what the intentions of his older brother were.

Dean threw himself down on his bed. "I dunno, it's kinda weird now that we know what we came hunting is human." He thought for a moment. "I think maybe we should hang around for a day or two, I wanna keep an eye on Alyssa and you can spend some time with Kia. Oh by the way, Alyssa said that if you hurt her sister she'll rip your jewels off."

"What?" Sam turned, his face incredulous.

"It's true, she said Kia's been hurt before."

A short while later the brothers had settled down to sleep. Sam lay in the dark, Dean's steady breathing the only sound. His mind chased itself in circles over what Dean had told him. He couldn't help wonder what had happened to Kia to drive Alyssa to such levels of protectiveness. Sighing, he turned over and attempted to sleep deciding that he would find out if she wanted to talk about it.


Alright guys so tell me what you think.
